Note: The flange types shown are only a small part of the range covered in BS EN 1092-1.

type 05 is a blank flange
type13 is a screwed boss flange
type 02 is a loose plate flange used with either
a type 32 weld on plate collar or
a type 33 lapped pipe end
a type 04 flange is a loose flange for use with a
type 34 a weld-neck collar
type 21 is an integral flange

The Facings shown are type B (Raised Face). Other Facings include:
Type A..Flat:  Type C..Tongue:   Type D..Groove   Type E..Spigot:  :Type F..Recess:   Type G..O-ring Spigot:  Type H.,0-ring Groove:

A typical designation for a flange would be BS EN 1092-1/01B/DN150/PN25/ */S235JR
Key: = Standard No/Flange Type & Face Type / Nominal Size/ Pressure Rating/*/ Material Designation.
* Normally not used.   For 01 type flanges above 600 mm the bore B1 would be specified here .   * for type 11 and 31 the neck thickness (S) is specified here.
